Surfboard with the Function of Speed Measurement

ABSTRACT

The present invention is about a surfboard, especially the one that can measure the surfing speed by itself. This “surfboard with the function of speed measurement” comprises a surfboard body and a speed meter fitted to the surfboard body that can measure the surfing speed by itself and record the surfing speed and relevant data. Advantages of this invention would be no need for additional speed measuring devices and assistance from other people. The surfer can obtain the surfing speed and relevant data while surfing, which will be shown on the LCD display screen on the surfboard.

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

This invention is about a surfboard, especially the one that can measurethe surfing speed by itself.

2. Description of Related Arts

Surfing is a very tense and exciting water sport, during which thesurfer usually stands on a narrow and long surfboard, riding the waveand skimming over the water. In addition, there is another type ofsurfing, so called “body surfing”, during which surfers surf without theuse of the surfboard. When surfing, the surfer needs to accurately seizethe timing to surf and to quicky act upon it, and to know how to keepthe body balance at the same time. Nowadays, surfing has become afashionable sport, and surfers enjoy surfing very much. However, withthe use of conventional surfboard, surfers can only obtain flow balanceand turbulence while surfing. Sufers don't know the surfing speed andthe numerical data unless depending on additional instruments andassistance from other people, Taking the deficiency of conventionalsurfboards into consideration, the inventor has made this inventioncalled “surfboard with the function of speed measurement”.

SUMMARY OF THE PRESENT INVENTION

This invention is to improve the deficiencies of the above-mentionedconventional technologies, and to offer a surfboard that can measure andrecord the surfing speed and the relevant data.

This invention adopts the following technical solutions to solvetechnical problems:

The surfboard with the function of speed measurement comprises asurfboard body and a speed meter fitted to the surfboard that canmeasure the surfing speed and record the relevant data.

The said speed meter fitted to the surfboard comprises a LCD displayscreen, a PCB board for performing functions in the circuit, a PCBenclosure for fixing the PCB board, and waterproof PVC keys. Inside thespeed meter, there is a power supply device, comprising a power supply,spring plates for conducting electricity, a power cap, and a waterproofseal ring. The power cap is screwed to the surfboard body.

There is a gripper device on the surface of the surfboard body forfitting the whole speed meter, which will couple the speed meter and thesurfboard body more tightly and enable the surfer to operate the speedmeter in a more convenient way. Besides, the surfer can also use anout-hung speed meter, which is to hang the speed meter onto thesurfboard body.

Advantages of this invention “surfboard with the function of speedmeasurement” would be no need for additional speed measuring devices andassistance from other people. The surfer can obtain the speed andrelevant data while surfing, which will be shown on the LCD displayscreen on the surfboard.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Further illustration on this invention “surfboard with the function ofspeed measurement” according to FIGS. 1 through 3:

A surfboard with the function of speed measurement comprises a surfboardbody (10) and a speed meter (20) fitted to the surfboard body (10) thatcan measure the surfing speed by itself and record the surfing speed andrelevant numerical data.

The speed meter (20) fitted to the surfboard body (10) comprises a LCDdisplay screen (25), a PCB board (21) for performing functions in thecircuit, a PCB enclosure (22) for fixing the PCB board (21), andwaterproof PVC keys (23). Inside the speed meter (20), there is a powersupply device (24), comprising a power supply (241), spring plates (242)for conducting electricity, a power cap (243), and a waterproof sealring (244). On the bottom side of the speed meter (20), there is afixing board (26), which is used for fixing the LCD display screen (25)and the PCB board (21). In addition, a seal ring (27) is used in thepower cap (243) for waterproof purpose. The power cap (243) is fixed tothe surfboard body with a screw (28) and a nut (29).

There is a gripper device (11) on the surfboard body (10) for fittingthe whole speed meter (20), which will couple the speed meter (20) andthe surfboard body (10) more tightly and allow the surfer to operate thespeed meter (20) in a more convenient way. Besides, to accommodatevarious needs, the surfer can also use an out-hung speed meter (20),which is to hang the speed meter onto the surfboard body (10).

FIG. 3 shows the work flow of the speed meter (20): First, the sensor(1) converts motion signals into corresponding electric signals andsends three sets of signals corresponding with X, Y and Z axisesrespectively to the micro-processor (2), which will conductanalog-to-digital conversion and process these signals with theoperational software. After this step, relevant accelation data will becalculated out. Next, resulting data will be shown on the LCD displayscreen (3) and saved in the memory (5). The power supply controller (4)will provide power to the above-mentioned components. Press the key (6)to turn on/off the micro-controller (2).

What is described above is just a preferred embodiment of this invention“surfboard with the function of speed measurement”, and it doesn'trestrict the technical scope of this invention. Any minor alteration,equal change or modification to the above-mentioned embodiment based onthe technical essence of this invention is still within the scope of thetechnical solution of this invention.
